Who cannot join
- Severely Compromised Remaining Teeth: If the remaining teeth have poor prognosis due to extensive decay or severe periodontal disease.

About this study
Official title: Effect of Scanning Technology on the Accuracy of Digitally Customized Intraradicular Attachments: A Cross Overstudy
This study aims to evaluate the accuracy of intra-radicular attachments fabricated by direct scanning using three different scanners in vivo. The primary outcome will be the accuracy of the fabricated attachments, while secondary outcomes will includepatient-reported comfort during procedure of taking intraradicular attachment conventional impression and direct scanning.
Read the detailed description
The fabrication of intra-radicular attachments is a critical step in restoring endodontically treated teeth. The accuracy of these restorations directly impacts their clinical performance, including retention, marginal fit, and long-term success. With advancements in digital dentistry, intraoral scanners (IOS) have become increasingly popular for direct scanning of intra-radicular preparations. However, the accuracy of these scanners varies depending on their technology, software, and clinical conditions

What is being measured
The primary outcome is the main question the study is designed to answer.
Accuracy
measure accuracy between the dimension of the prepared canal gained by intra-radicular impression and the dimension of the prepared canal directly by two different types of intraoral scanners
Measured: Immediately after scanning.
Secondary outcomes (1)
Patient-reported comfort
Patient-reported comfort (assessed via a Likert scale questionnaire) Scaled from 0-100 The highest score means excellent The lowest score means unsatisfactory
Measured: Immediately after impression taking and scanning.

Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Accuracy (time frame: Immediately after scanning.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
